VESSEL FOR PACKING AND STORlNG WASHINQ-POWDERS CONTAINING ALKALINE PEROXIDS.

Patented April 24, 1906.

- Application filed omw 18,1905. Serial Fo- 283,060.

-To; all whom it may concern:

Be it known that I, JULIUS VON Konros- WARTER, a subject of the Grand Duke of Saxe-Coburg, residing at Hanover, German Empire, have invented new and useful Improvements in Methods of Packing and Stor-' mg Washi -Powder Containing Alkaline Peroxids an Devices Therefor, of which the following is a specification.

This invention relates to a method of packing and storin washing-powder having as a constituent sodium superoxid or other alkali superoxid and a device therefor.

This method consists in the separate compartments containing the'constituents composing the washing-powder having such a position relative to one another that the superoxid only encounters the other constituents at the moment of use; when simultaneously with the openin of the packet or vessel the contents of t e separate com art- I ments containing the constituents o the washing-powder are mixed.

The excellent pro erties of alkali su eroxid, more particular y sodium superoxi as a bleaching agent have long been known; but superoxid mixed with soap as a washin ma terial for household use has not been ound suitable because owin to the presence of moisture in the soap ecom osition of the sodium superoxid is unavoi able. The superoxid must therefore be kept separate and unmixed with the soap without, however, the superoxid coming in a ure condition into the hands of the user, ecause on the one hand in a pulverulent or dusty condition it has a highly irritant action on the breathin organs and on the other hand in contact wit moist organic substancessuch as flour, sugar, paper, and the likeit is liable to spontaneous combustion.

Now this invention has for its object tomake sodium superoxid as a very mild and yet powerful bleaching agent in combination with pure soap powder applicable as wash-' ingowder for general use, while of course the 'ability to spontaneous combustion, the caustic or u'ritant action, and the liability to decompose must be made innocuous without affecting in any way the industrial use of the product. This is done by storing or packing the superoin'd and the substances to be mixed with it-such, for instance, as soap or soap and free fatty acid (and soa -forming or saponaceous substances)-in 0. cl sel provided with several separate compartosed ves-,

ments in such a way that the separate compartments of the vessel containing the constituents of the washing-powder are arranged in such a way relatlve to one another that simultaneously with the opening of the package or vessel the contents ofthe separate compartments are compulsorily mixed in order that thejsuperoxid m a pure condition ma never reach thehands of the user unmixe At the same time this method of packing has the advantage that the superoxid retains its entire contents of active oxygen and full eflectiveness when mixed with soa is form of construction of a containing and packing vessel based on the principle hereinefore developed is shown as an example in theaccompanying drawings, in which Figure 1 is a vertical central section, and 2 a horizontal section on the line a: 2; of

An external, preferabl cylindrical, vessel (1, which concentrically inc oses a tube b, preferably open at the bottom, inwhich the superoxid is placed, serves for receiving the soap powder. The tube bis attached to the lid or cover 0, so that when the lid or cover is lifted off the pipe is drawn out with it and discharged. An expelling or discharging appliance dis attached,bymeans of a wire e, to the bottom of the vessel a and expels the superoxid w en the pipe b is drawn out, a rotaly motion being imparted to the expeller, if esired, by hand.

The charging of the packing-vessel is done before the bottom f is put on. The vessel a is placed upside down with its lid secured or closed, and the expellin device d is inserted in the tube, after whic the outer compartment of the vessel is' filled with soap powder or a mixture of soap and stearic acid and the inner pipe b with su eroxid. The bottom f is then put on, whic has a hole for the passage of the wire e and fits, b means of its projecting parts,into the vesse a and the pig; b. The bottom f extends, as shown in fu l es in Fig. 1, all round the vessel 0. as an edge or rim. This projecting edge or rim is then folded over or bent round and the end of the wire a bent round and soldered down, as shown in dotted lines. The packing is now completed.

If it be desired to re eatedly use the package or container, the ottom f is only provided with a projecting part at the ed e and the tube b is removably attached to the 'd c- IOO for instance, by means of a bayonet-joint or the likeso that the box may be filled from above.

What I claim is 1 1. A receptacle for packing and storing washing-powder containing an alkali supe:-

oxid consisting of an outer vessel, in removable cover therefor and an inner vessel depending from said cover and removable therewith, the lower end of said inner vessel being normally closed by the bottom of the outer vessel.

2. A receptacle for packing and storing was -powder, consisting of a vessel, 9. cover t erefor, a tube connected to the cover I 5 and said tube having its lower end open, an expeller in said tube and a wire connected to the e ller and extending through the bottom 0 the vessel.

In testimony whereof I have signed my 20 name to this specification in the presence of two subscribing witnesses.
